How to use HPC available at IIT Delhi?

This is going to be a series as there are so many steps to follow.

In this blog I am going to cover, how one can use the Internet on the HPC Nodes. There are two ways to do so. On the HPC website, with your VPN, you can access the tutorials on how to use HPC. There you will find one of the method explained well.

The other method is using a proxy script. The scripts are available to download from the following link:

These are the port numbers according to your course

After you enter your password, you will get a text with proxy login message.

Notedown the proxy ip & port ( Proxy_IP is 10.10.79.29 and Proxy_port is 3128) & the login node’s hostname (login02).

From a new terminal , log in to the hpc account & go to the same login node (login02) where Linux is running & set http_proxy , https_proxy environment variable within your terminal as:

[user1@login02]$ export http_proxy=10.10.79.29:3128
[user1@login02]$ export https_proxy=10.10.79.29:3128

Now you will be able to use the internet on your HPC Node.

Note: Do not use your internet on login nodes. Use it only on your dedicated node where you are connecting with ssh after requesting a job. If you use it on login nodes, then anyone can use your internet and you get a limited quota of internet for a week( or month) to use on HPC.
